Too early or is this normal?

My boobs have been sore and enlarged since Jan 18.

My nipples are big, round, purple and tingling all the time.

Occasionally mild cramping but nothing crazy, sometimes I think it’s just gas.

My mood swings are ridiculous.

Low blood pressure and fatigue.

Isn’t it too early for symptoms?

Isn’t it too early for a test?

I took a test just for the heck of it and it was negative.
